Application filed March 2, 1914. Serial No. 821,943.

To all whom if m (13 concern Be it known that I, JULIUS Rnrznarr, a citizen of the United States. residing at Luxemburg, in the county of Kewaunee and State of Visconsin, have invented certain new and useful Improvements in Threshing-Machines. of which the following is a specification, reference being had to theaccompanying drawings.

This invention relates to certain improvements in threshing machines and has relation more particularly to a device of this general character especially designed and adapted for use for stripping vines. such as pea vines, and to seed or hull the separated pods; and the objectof the invention is to provide a device of this general character having novel and improved means whereby the complete operation is afforded in substantially an automatic manner after the vines are placed upon the carrier to be dis charged within the machine proper.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved threshing machine whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use. all as will be' hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

In order that my --invention may be the better understood. I will now proceed to describe the same. with reference to the accompanying drawings. wherein Figure l is a view in side elevation of a threshing machine constructed in accordance with an embodiment of my invention, certain of the inclosed parts being indicated by dotted lines in a somewhat diagraphic manner; Fig. 2 is a longitudinal vertical section taken through the device as illustrated in Fig. l at substantially the transverse center thereof; Fig. 3 is a sectional view taken substantially on the line 3 3 of Fig. 2; Fig. 4 is a fragmentary view in top plan of the upper portion of the. carrier as herein disclosed; Fig. 5 is a view in top plan of the inclined pan herein included; Fig. 6 is an enlar ed view. detached. in perspective of one of the beater blades herein embodied; and Fig. 7 is a fragmentary view in top plan of the device, illustrating (ti ellitgln details of my invention as herein set ort As disclosed in the accompanying draw-- ings, 1 denotes a supporting frame, preferably of a. skeleton type, arranged to best meet the requirements of practice. believed to be unnecessary to give a detailed description of the supporting frame as the exact arrangement thereof will depend upon the particular conditions, al-

though it may be well to state that suchframe includes the upright sections 2-2 whereby certain operative parts of the device nia v be operatively supported. EX- tendmg upwardly from one end of the sup porting frame 1. on a desired inclination. is a carrier frame including the side-boards 4 and operatively supported by such sideboards 4 adjacent the opposite extremities of the frame 3 are the shafts 5 having suitably afl'ixed theret between the side-boards 4 and in close proximity thereto, the sprocket wheels (3 around which pass the endless chains 7, such chains being united by the transverse strips 8 whereby the vines deposited upon the carrier frame are caused to be conveyed upwardly and discharged within the threshing machine proper. As the vines drop from the upper end of the carrier they will fall upon the spreader roller 9 mounted between certain of the ver,

tical portions 2 of the supporting frame and positioned in close proximity to the upper extremity of the carrier frame 3 and rotated in a manner to be hereinafter more particularly referred to. The spreader roller 9 is adapted to have a peripheral speed greater than the speed of travel of the chains 7. -The spreader roller 9 causes the vines to be discharged upon the uppcrbcater roller 10 positioned slightly to the rear of the spreader roller and also positioned slightly thcrebolow. such beater roller 10 coacting with the concave or ripping board 11. The concave or ripping board 11 serves to guide or direct the vines into contact with the lower or second beater roller 12 which coacts with the concave or ripping board 14 whereby it will be perceived that the coaction between the beater rollers 10 and 12 with their-concaves or ripping boards 11 and 14, respectively, afford an effective .means whereby the peas are taken from within their hulls or pockets. In order to assure the delivery of the vines from the upper beater roller 10 to the lower beater roller 12, T find it. of particular advantage to have depending from the lower marginal iortion of the upper concave or ripping board 11, the apron 15 such apron depending on a desired incline and terminating in close proximity to the lower beater roller 12. as is believed to be clearly illustrated in the drawings.

The lower concave or ripping board 14 delivers the vinesand the separated peas upon the shakers 1t; directed rearward y of the frame 1 and disposed in substantial parallelism and in slightly spaced relation, the upper surface of such shakers being serrated, as indicated at 17, for purposes which are believed to be self-evident.

In a manner to be hereinafter more par ticularly referred to, the shakers 1b are caused to oscillate, which movement serves to direct the vines rearwardly of the frame whereby they may be discharged from the machine while the separated peas fall from the sections and drop upon the pan 18 positioned below and common to all of the shale ers 16. The pan 18 is adapted to be reciprocated in a manner which will also hereinafter be more fully set forth, and serves to work the separated peas forwardly thereof so that they will be discharged upon the pan 19 disposed on a rearward and downward incline and intersecting the forward end of the pan 18 but affording a space therebctween so that the separated peas deposited upon the pan 19 may be deflected thereby upon the endless apron 20 disposed on an upward and rearward incline with the upper stretch thereof travelin rearwardly. The lower marginal portion of the pan 19 is provided with a plurality of elongated tines or fingers 21 disposed in close proximity one with the other and so positioned as to intersect the draft or air blast created by the fan 22 operatively supported in the forward portion of the frame 1 between certain of the vertical sections 2 and below the pan 19 whereby it will be readily perceived that dirt or other foreign substances accompanying the separated peas will be blown rearwardly upon the endless apron 20 which is formed preferably of canvas and will be conveyed thereby to the rear of the frame 1 and suitably discharged, as is believed to be self-evident, while the separated peas, owing to the inclination of the upper stretch of the endless apron 20, will be caused to discharge upon the discharge conveyor 23 disposed transversely of the frame 1 and below the lower portion of the apron 20.

As herein disclosed, the shakers 16 operate in unison but alternate shakers travel in opposite directions and, as herein set forth, this movement is accomplished by having the opposite extremities of such shakers operatively connected with the crank shafts 24, the cranks of each of the shafts being correspondingly directed. Each of the shafts 21 has a projected extremity on which is fixedly secured a drum 26 around which is directed a belt 27 whereby it will be perceived that such shafts are both positively driven. One of such shafts 24, preferably the rear shaft, is also provided with a sprocket wheel 28 around which is directed the sprocket chain 25) which is also disposed around the sprocket wheels 30 opcrativcly supported by the frame 1. The shaft 4.4 of one of the beater rollers, preferably the for ward one, constitutes the drive shaft of the machine and is adapted to be connected in any desired manner but. preferably by a belt, as at 56, with any suitable source of power. The pan 18, as hereinbefore stated, is mounted for reciprocal movement and for this reason has its rear portion loosely rested upon the idler wheels or rollers 32 suitably supported by the frame 1, while the forward extremity of such pan is pivotally connected through the medium of the extensions or arms 33 with the lower portion of the pan 19 which is hingedly connected, as at 34, at its upper end with the transverse rod 35 disposed transversely of the frame 1 whereby it will be readily perceived that the pan 15) is agitated in unison with the pan 18. The shaft 36 of the rear sprocket wheel 30 is provided with a pulley or drum 37 around which is directed a belt 38 which also passes around a drum or pulley 39 suitably aflixed to the projected portion of a shaft 10 disposed transversely of the frame 1 and below the pan 18, such shaft being provided at substantially its longitudinal center with the crank 11 pivotally engaged by an extremity of a pitman 412, the opposite extremity of such pitman being pivotally connected to the under surface of the pan 18 through the medium of a bracket or mounting 43 suitably secured thereto. By this arrangement, the manner in which the pans 18 and 19 are caused to move will be readily perceived.

The shafts 4.4. of the spreader roller 9 and the heaters 10 and 12 are also provided with suitable drums or pulleys 45, around which is properly directed a belt 46, such belt being also disposed around a drum or pulley 26, preferably the forward one, whereby it will be readily perceived how such spreader roller 9 and heater rollers 10 and 12 are caused to rotate. The belt -16 is also directed around a drum or pulley 47 positioned on the shaft 418 of the fan 22. On the opposite extremity of the shaft 44 of the spreader roller 9 is affixed a drum 4-9 around which is directed a belt 50 which is also properly directed around a drum or pulley 51 fixed to the adjacent extremity of the uppermost shaft 5, whereby it will be readily perceived the manner in which the chains 7 are caused to be driven. The fan 22 may be of any ordinary or preferred construction and for this reason it is not believed necessary to give a detailed description thereof. This is also true of the beater rollers 10 and 12 but it may be well to state that I prefer to construct the same as illustrated in the accompanying drawings. I also find it of advantage to employ a. spreadin; means in connection with the carrier. hereinbefore described. and, as herein disclosed. such means comprises two spreading rollers 51 disposed in upwardly diverging planes and positioned adjacent the upper extremity of the carrier and. as herein dis closed. are opcratively supported by the frame 52 suitably connected to the sideboards 4 of the carrier frame 2% and having the upper extremities of their shafts 53 in suitable gear connection. as indicated at 5-1. with the uppermost shaft 3. the advantages and purposes of these additional spreadingrollers 51 being. it is thought. self-evident. I also tind it of advantage to provide the shield 55 operatively connected to the frame 1 and to the upper longitudinal portion of the concave 11. such shield having its upper extremity suitably directed a predeteri-nined extent over the upper extremity of the car rier frame 3 whereby it will be seen that the vines discharged by the carrier will be assured of proper entrance within the threshing machine proper.

From the foregoing des ription. it is thought to be obvious that a threshing machine constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it accomplishes the functions desired thereof. and by reason of the substantially automatic manner in which it operates. and it will also be obvious that my invention is susceptible of some hange and modification without material departure from the principles and spirit thereof and for this reason i do not wish to be understood as limiting myself to the precise arrangen'icntand formation of the several parts herein shown in carrying out my invention in practice.
